Cisco ONS 15216 EDFA2/EDFA2-A Operations Guide, R2.4
July 2004
Chapter 3 Installation
3.2.2 Rack Installation and Power Supply Connection Procedures
Circuit Overloading—Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of circuits might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment nameplate ratings should be used.
Reliable Earthing—Reliable grounding of rack mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch circuit
(i.e., use of power strip, etc.).
Warning
The ONS 15216 EDFA2 is intended for installation in a restricted access area. A restricted access area
is where access can only be gained by service personnel through the use of a special tool, lock, key,
or other means of security. A restricted access area is controlled by the authority responsible for the
location.
3.2.2 Rack Installation and Power Supply Connection Procedures
Warning
Before performing any of the following procedures, ensure that the power is removed from the DC
circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the
DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit
breaker in the OFF position.
Follow these steps to install the ONS 15216 EDFA2 into the rack and correctly set up the power supply:
Step 1 Mount the ONS 15216 EDFA2 in the rack (19 inches or 23 inches reversible ears). Empty rack space is
not required above or below the ONS 15216 EDFA2.
Step 2 Connect the –48 VDC power cable to the office fuse panel (user-provided).
a. 1.5A fusing is required (user-provided).
b. Use 18 AWG stranded wire (and wire lugs as appropriate).
Step 3 Connect power cable from the office fuse panel to the power bus A terminals on the ONS 15216 EDFA2.
See Figure 2-2 on page 2-6.
Step 4 Repeat Step 3 for power bus B.
Step 5 Connect the facility ground to the ONS 15216 EDFA2 side panel ground using #10-32 x 3/8-inch
fasteners with lock washers and ground lugs, or connect to the rear panel ground using ring lugs for #8
studs.
Step 6 Insert 1.5A fuses into the fuse panel (user-provided).
Step 7 While the ONS 15216 EDFA2 is booting, the following LED behavior should be observed:
a. The POWER (green), FAIL (red), and LOS (yellow) LEDs all turn on.
b. The POWER LED flashes for approximately 1 second, the FAIL LED flashes for approximately 1
second, and the LOS LED flashes for approximately 1 second.
c. The POWER, FAIL, and LOS LEDs all turn on.
d. The alarm relays click, indicating that boot process has completed. This occurs because the software
sets the relays to their default state and then determines the relay settings based on alarm conditions.
